Abstract
Description
467 419 2 Stàngen 13 är, lämpligen vid dess mitt, försedd med ett parti l4 med större diameter än övriga delar av stången. Ett lämpligt sätt att ástdkomma detta förtjockade parti är att friktionssvetsa två stänger för bildande av stången 13. Rördelen 4 är försedd med en diameterreduceríng 15 som vid uppåtriktad borrning är belägen nedanför partit 14 på stången 13. Rördelen 5 är försedd med en diameterreduceríng 16 försedd med ett antal spår 17 för passage av spolvätska. Mellan diameterreduceringarna 15,16 har rörpaketet en invändig diameter som är större än diametern på partit 14 så att spolvätska kan passera förbi partit 14. Vid uppàtriktad borrning pressar stången i borrsträngskomponenten nedanför upp stången 13 till ett läge såsom visat i fig 2 varigenom spolvätska kan passera genom borrsträngen till borrkronan 3. The rod 13 is, suitably at its center, provided with a portion 14 of larger diameter than other parts of the rod. A suitable way of accessing this thickened portion is to friction weld two rods to form the rod 13. The pipe part 4 is provided with a diameter reduction 15 which, when drilled upwards, is located below the portion 14 of the rod 13. The pipe part 5 is provided with a diameter reduction 16 provided with a number of grooves 17 for the passage of flushing liquid. Between the diameter reducers 15,16, the pipe package has an inner diameter which is larger than the diameter of the portion 14 so that flushing liquid can pass past the portion 14. During upward drilling, the rod in the drill string component below presses up the rod 13 to a position as shown in Fig. through the drill string to the drill bit 3.
Vid skarvning av borrsträngen backas bergborrmaskinen så att stången 13 sjunker från det i fig 2 visade läget till ett läge där partit 14 kommer till anliggning mot díameterreduceringen 15 så att tätning åstadkommes mellan stången 13 och rörpaketet. Härigenom förhindras att spolvätska ovanför tätníngen rinner ut ur borrsträngen. »_When splicing the drill string, the rock drilling machine is reversed so that the rod 13 sinks from the position shown in Fig. 2 to a position where the portion 14 comes into abutment against the diameter reduction 15 so that a seal is provided between the rod 13 and the pipe package. This prevents flushing fluid above the seal from flowing out of the drill string. »_
